Because we miss to wipe the remainder of i->addr[] in packet_mc_add(), pdiag_put_mclist() leaks uninitialized heap bytes via the PACKET_DIAG_MCLIST netlink attribute. Fix this by explicitly memset(0)ing the remaining bytes in i->addr[].

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2016-04-13 This series contains updates to i40e, i40evf and fm10k. Alex fixes a bug introduced earlier based on his interpretation of the XL710 datasheet. The actual limit for fragments with TSO and a skbuff that has payload data in the header portion of the buffer is actually only 7 fragments and the skb-data portion counts as 2 buffers, one for the TSO header, and the one for a segment payload buffer. Jacob fixes a bug where in a previous refactor of the code broke multi-bit updates for VFs. The problem occurs because a multi-bit request has a non-zero length, and the PF would simply drop any request with the upper 16 bits set. ==================== Signed-off-by: David S.

For local routes that require a particular output interface we do not want to cache the result. Caching the result causes incorrect behaviour when there are multiple source addresses on the interface. The end result being that if the intended recipient is waiting on that interface for the packet he won't receive it because it will be delivered on the loopback interface and the IP_PKTINFO ipi_ifindex will be set to the loopback interface as well. This can be tested by running a program such as "dhcp_release" which attempts to inject a packet on a particular interface so that it is received by another program on the same board. The receiving process should see an IP_PKTINFO ipi_ifndex value of the source interface (e.g., eth1) instead of the loopback interface (e.g., lo). The packet will still appear on the loopback interface in tcpdump but the important aspect is that the CMSG info is correct.

The VF uses a multi-bit update request to clear unused VLANs whenever it resets. However, an accident in a previous refector broke multi-bit updates for VFs, due to misreading a comment in fm10k_vf.c and attempting to reduce code duplication. The problem occurs because a multi-bit request has a non-zero length, and the PF would simply drop any request with the upper 16 bits set. We can't simply remove the check of the upper 16 bits and the call to fm10k_iov_select vid, because this would remove the checks for default VID and for ensuring no other VLANs can be enabled except pf_vid when it has been set. To resolve that issue, this revision uses the iov_select_vid when we have a single-bit update, and denies any multi-bit update when the VLAN was administratively set by the PF. This should be ok since the PF properly updates VLAN_TABLE when it assigns the PF vid. This ensures that requests to add or remove the PF vid work as expected, but a rogue VF could not use the multi-bit update as a loophole to attempt receiving traffic on other VLANs.

commit b7d3e3d3 ("net: thunderx: Don't leak phy device references on -EPROBE_DEFER condition.") incorrectly moved the call to of_node_put() outside of the loop.

This patch addresses a bug introduced based on my interpretation of the XL710 datasheet. Specifically section 8.4.1 states that "A single transmit packet may span up to 8 buffers (up to 8 data descriptors per packet including both the header and payload buffers)." It then later goes on to say that each segment for a TSO obeys the previous rule, however it then refers to TSO header and the segment payload buffers. I believe the actual limit for fragments with TSO and a skbuff that has payload data in the header portion of the buffer is actually only 7 fragments as the skb->data portion counts as 2 buffers, one for the TSO header, and one for a segment payload buffer.

f1705ec1 added the option to retain user configured addresses on an admin down. A comment to one of the later revisions suggested using the IFA_F_PERMANENT flag rather than adding a user_managed boolean to the ifaddr struct. A side effect of this change is that link local and loopback addresses are also retained which is not part of the objective of f1705ec1. Add check to drop those addresses.

If a requested extension exists as module and is not loaded, ebt_check_match() might accidentally use an NFPROTO_UNSPEC one with same name and fail. Reproduced with limit match: Given xt_limit and ebt_limit both built as module, the following would fail: modprobe xt_limit ebtables -I INPUT --limit 1/s -j ACCEPT The fix is to make ebt_check_match() distrust a found NFPROTO_UNSPEC extension and retry after requesting an appropriate module.

ifupdown2 found a kernel bug with IPv6 routes and movement from the main table to the VRF table. Sequence of events: Create the interface and add addresses: ip link add dev eth4.105 link eth4 type vlan id 105 ip addr add dev eth4.105 8.105.105.10/24 ip -6 addr add dev eth4.105 2008:105:105::10/64 At this point IPv6 has inserted a prefix route in the main table even though the interface is 'down'. From there the VRF device is created: ip link add dev vrf105 type vrf table 105 ip addr add dev vrf105 9.9.105.10/32 ip -6 addr add dev vrf105 2000:9:105::10/128 ip link set vrf105 up Then the interface is enslaved, while still in the 'down' state: ip link set dev eth4.105 master vrf105 Since the device is down the VRF driver cycling the device does not send the NETDEV_UP and NETDEV_DOWN but rather the NETDEV_CHANGE event which does not flush the routes inserted prior. When the link is brought up ip link set dev eth4.105 up the prefix route is added in the VRF table, but does not remove the route from the main table. Fix by handling the NETDEV_CHANGEUPPER event similar what was implemented for IPv4 in 7f49e7a3 ("net: Flush local routes when device changes vrf association") Fixes: 35402e31 ("net: Add IPv6 support to VRF device") Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S.

Vivek reported a kernel exception deleting a VRF with an active connection through it. The root cause is that the socket has a cached reference to a dst that is destroyed. Converting the dst_destroy to dst_release and letting proper reference counting kick in does not work as the dst has a reference to the device which needs to be released as well. I talked to Hannes about this at netdev and he pointed out the ipv4 and ipv6 dst handling has dst_ifdown for just this scenario. Rather than continuing with the reinvented dst wheel in VRF just remove it and leverage the ipv4 and ipv6 versions.

Stop all Ethernet RX Queues before freeing up various Ingress/Egress Queues, etc. We were seeing cases of Ingress Queues not getting serviced during the shutdown process leading to Ingress Paths jamming up through the chip and blocking the shutdown effort itself. One such case involved the Firmware sending a "Flush Token" through the ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to make sure there weren't any remaining TX Work Requests in the pipeline. But the return path was stalled by Ingress Data unable to be delivered to the Host because those Ingress Queues were no longer being serviced.

When using the PTP fpga to hps clock source for the stmmac module the appropriate bit in the System Manager FPGA Interface Group register needs to be set. This is not set by the bootloader setup when the HPS emac pins are being for this emac module. This allows the PTP clock to be sourced from the FPGA and also connects the PTP pps and ext trig signals to the stmmac PTP hardware. Patch proposed by Phil Collins.

All existing users of NETLINK_URELEASE use it to clean up resources that were previously allocated to a socket via some command. As a result, no users require getting this notification for unbound sockets. Sending it for unbound sockets, however, is a problem because any user (including unprivileged users) can create a socket that uses the same ID as an existing socket. Binding this new socket will fail, but if the NETLINK_URELEASE notification is generated for such sockets, the users thereof will be tricked into thinking the socket that they allocated the resources for is closed. In the nl80211 case, this will cause destruction of virtual interfaces that still belong to an existing hostapd process; this is the case that Dmitry noticed. In the NFC case, it will cause a poll abort. In the case of netlink log/queue it will cause them to stop reporting events, as if NFULNL_CFG_CMD_UNBIND/NFQNL_CFG_CMD_UNBIND had been called. Fix this problem by checking that the socket is bound before generating the NETLINK_URELEASE notification.

Currently on high rate SCTP streams the heartbeat timer refresh can consume quite a lot of resources as timer updates are costly and it contains a random factor, which a) is also costly and b) invalidates mod_timer() optimization for not editing a timer to the same value. It may even cause the timer to be slightly advanced, for no good reason. As suggested by David Laight this patch now removes this timer update from hot path by leaving the timer on and re-evaluating upon its expiration if the heartbeat is still needed or not, similarly to what is done for TCP. If it's not needed anymore the timer is re-scheduled to the new timeout, considering the time already elapsed. For this, we now record the last tx timestamp per transport, updated in the same spots as hb timer was restarted on tx. Also split up sctp_transport_reset_timers into sctp_transport_reset_t3_rtx and sctp_transport_reset_hb_timer, so we can re-arm T3 without re-arming the heartbeat one. On loopback with MTU of 65535 and data chunks with 1636, so that we have a considerable amount of chunks without stressing system calls, netperf -t SCTP_STREAM -l 30, perf looked like this before: Samples: 103K of event 'cpu-clock', Event count (approx.): 25833000000 Overhead Command Shared Object Symbol + 6,15% netperf [kernel.vmlinux] [k] copy_user_enhanced_fast_string - 5,43% netperf [kernel.vmlinux] [k] _raw_write_unlock_irqrestore - _raw_write_unlock_irqrestore - 96,54% _raw_spin_unlock_irqrestore - 36,14% mod_timer + 97,24% sctp_transport_reset_timers + 2,76% sctp_do_sm + 33,65% __wake_up_sync_key + 28,77% sctp_ulpq_tail_event + 1,40% del_timer - 1,84% mod_timer + 99,03% sctp_transport_reset_timers + 0,97% sctp_do_sm + 1,50% sctp_ulpq_tail_event And after this patch, now with netperf -l 60: Samples: 230K of event 'cpu-clock', Event count (approx.): 57707250000 Overhead Command Shared Object Symbol + 5,65% netperf [kernel.vmlinux] [k] memcpy_erms + 5,59% netperf [kernel.vmlinux] [k] copy_user_enhanced_fast_string - 5,05% netperf [kernel.vmlinux] [k] _raw_spin_unlock_irqrestore - _raw_spin_unlock_irqrestore + 49,89% __wake_up_sync_key + 45,68% sctp_ulpq_tail_event - 2,85% mod_timer + 76,51% sctp_transport_reset_t3_rtx + 23,49% sctp_do_sm + 1,55% del_timer + 2,50% netperf [sctp] [k] sctp_datamsg_from_user + 2,26% netperf [sctp] [k] sctp_sendmsg Throughput-wise, from 6800mbps without the patch to 7050mbps with it, ~3.7%.

Specifics: - intel_pstate fixes for two issues exposed by the recent switch over from using timers and for one issue introduced during the 4.4 cycle plus new comments describing data structures used by the driver (Rafael Wysocki, Srinivas Pandruvada). - intel_idle fixes related to CPU offline/online (Richard Cochran). - intel_idle support (new CPU IDs and state definitions mostly) for Skylake-X and Kabylake processors (Len Brown). - PCC mailbox driver fix for an out-of-bounds memory access that may cause the kernel to panic() (Shanker Donthineni). - New (missing) CPU ID for one apparently overlooked Haswell model in the Intel RAPL power capping driver (Srinivas Pandruvada). - Fix for the PM core's wakeup IRQs framework to make it work after wakeup settings reconfiguration from sysfs (Grygorii Strashko). - Runtime PM documentation update to make it describe what needs to be done during device removal more precisely (Krzysztof Kozlowski). - Stale comment removal cleanup in the cpufreq-dt driver (Viresh Kumar). - turbostat utility fixes and support for Broxton, Skylake-X and Kabylake processors (Len Brown)" * tag 'pm+acpi-4.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (28 commits) PM / wakeirq: fix wakeirq setting after wakup re-configuration from sysfs tools/power turbostat: work around RC6 counter wrap tools/power turbostat: initial KBL support tools/power turbostat: initial SKX support tools/power turbostat: decode BXT TSC frequency via CPUID tools/power turbostat: initial BXT support tools/power turbostat: print IRTL MSRs tools/power turbostat: SGX state should print only if --debug intel_idle: Add KBL support intel_idle: Add SKX support intel_idle: Clean up all registered devices on exit. intel_idle: Propagate hot plug errors. intel_idle: Don't overreact to a cpuidle registration failure. intel_idle: Setup the timer broadcast only on successful driver load. intel_idle: Avoid a double free of the per-CPU data. intel_idle: Fix dangling registration on error path. intel_idle: Fix deallocation order on the driver exit path. intel_idle: Remove redundant initialization calls. intel_idle: Fix a helper function's return value. intel_idle: remove useless return from void function. ...

After commit f84bb1ea ("net: fix IFF_NO_QUEUE for drivers using alloc_netdev"), default qdisc was changed to noqueue because tuntap does not set tx_queue_len during .setup().
